Mercedes-Benz A-Class2020

Known issues

• Battery capacity degradation over time, particularly if not regularly charged or exposed to extreme temperatures; capacity loss of 5–15% within 5 years is not uncommon
• DCT (dual-clutch transmission) judder and hesitation during low-speed manoeuvres and electric-to-petrol power transitions
• High-voltage battery cooling system failures causing thermal management warnings and reduced electric-only range
• Charging port corrosion and intermittent charging faults, especially in humid/coastal Irish conditions
• Starter-generator (48V mild hybrid element) component failures requiring expensive replacement units
• Infotainment system software glitches affecting navigation, Bluetooth connectivity, and trip computer accuracy

Good for

• Low-emission urban commuting with full electric capability up to ~50 km on battery alone (if regularly charged)
• Company car tax benefits in 2020 due to sub-50 g/km CO2 emissions classification
• Premium interior, build quality, and driver assistance technology
